KEY POINTS
- Brent crude jumped 4.24% to near $95 a barrel Monday after Iranian state media reported Tehran was preparing to fully close the Strait of Hormuz.
- The International Energy Agency has called the Iran war the largest supply disruption in the history of the global oil market, with 100 million barrels of crude stranded on ships.
- Trump said a memorandum of understanding to reopen the Strait could be reached within a week, but traders remain skeptical, with Brent trading in a $15 range over the past month.
Brent crude surged 4.24% to $94.58 on Monday after Iranian state media reported that Tehran had suspended communications with Washington through intermediaries and was preparing to fully close the Strait of Hormuz. West Texas Intermediate crude rose nearly 6% to above $92, marking its sharpest single-session gain in three weeks.
The Strait of Hormuz is the most important oil chokepoint on the planet. Roughly 20 million barrels per day, or about one-fifth of global supply, moves through the narrow waterway between Iran and the Arabian Peninsula. A full closure would dwarf any supply disruption in modern history, and the International Energy Agency has already characterized the broader Iran conflict as the largest supply disruption ever recorded.
A Market Trading on Headlines
Oil has become the most headline-sensitive commodity on the board. Over the past month alone, Brent has swung in a roughly $15 range, from below $90 during peak optimism about a peace deal to above $100 when diplomatic hopes faded in mid-May. Monday's move was triggered by a report from Iran's state-affiliated Tasnim News Agency that Tehran and its regional allies were considering not just the Hormuz closure but also a blockade of the Bab el-Mandeb Strait, the alternate route connecting the Red Sea to the Gulf of Aden.
The reaction was immediate. Energy stocks in the S&P 500 caught a bid, and gasoline futures pushed higher. But the move was contained relative to what a full Hormuz closure would actually mean. That tells you the market is still pricing a deal as the base case.
President Trump added to the mixed signals Monday, posting on social media that negotiations with Tehran were proceeding constructively and that a memorandum of understanding to reopen the Strait could come within a week. At the same time, he instructed officials "not to rush into a deal." The diplomatic two-step has become the defining feature of this conflict for commodity traders.
The Stranded Oil Problem
Even if a deal materializes this week, the supply normalization timeline is measured in months, not days. Markets expect roughly 100 million barrels of crude oil currently stranded on ships to begin flowing once an agreement is in place. But industry estimates suggest three to six months will be needed to fully restore production, restart refineries, and clear the backlog. That lag means even a best-case deal scenario keeps prices elevated through the summer.
Gas prices at the pump have already hit $4 per gallon nationally, a 30% increase driven entirely by the Iran conflict. Headline inflation has been pushed higher by energy costs, complicating the Federal Reserve's calculus on rate policy and adding a political dimension to what is already the most complex geopolitical crisis in over a decade.
The Binary Setup
Energy traders now face a genuinely binary outcome in June. A deal that reopens the Strait could send Brent crashing toward $80 as stranded crude floods the market and speculative longs unwind. A breakdown in talks, or worse, a confirmed full closure, could push prices to $120 or beyond, levels not seen since the 2022 Russia-Ukraine spike.
The options market reflects this uncertainty. Implied volatility on Brent crude futures is at its highest level since March, with the 25-delta put-call skew heavily favoring calls. Traders are paying up for upside protection, a signal that the smart money sees the tail risk as skewed to the upside in prices.
Watch for any official statement from the Iranian foreign ministry this week. The diplomatic calendar is compressed, and Trump's suggestion that a memorandum could come within seven days sets a hard clock. If nothing materializes by next Monday, expect the Hormuz premium in oil to ratchet higher — fast.
